Electronic and Pneumatic Controls

IMG_1928aPneumatic Systems comprise a huge number of technologies and integrations that use pressurized air to either power or drive them. In the case of pneumatic controls and instrumentation, pneumatics are used to communicate process variable commands to control valves. Pneumatic logic is used in many machine applications. While being explosion proof and intrinsically non-hazardous for dangerous areas such as in refineries and chemical plants, pneumatics are relatively easy to install and maintain since the signals are carried through simple low pressure tubes.

The electronic control unit evaluates the signals from the sensors to determine the operating conditions, and controls actuators to move dampers and valves that control the volume, temperature and direction of the air delivered by the system.
